Bolt on an additional 10+ Horsepower at the wheels!

This BMW 135 & 335 light weight crank pulley is designed to regain wasted horsepower and channel that power to your wheels by significantly reducing the weight and moment of inertia of the factory pulley.
It’s precisely machined for a direct fit and is visually identical to stock.

Made from hard anodized black 6061 T6 billet aluminum.
